Abstract

(57) [Summary] This bulletin contains application data before electronic filing, so abstract data is not recorded.

Description

[Detailed Description of the Invention] [Summary] A connecting rod is provided that rotatably connects one end of the door and a predetermined position of the casing, and the connecting rod is rotated to move the door to the rotating side of the casing. It moved along the body side wall and was able to polymerize.

[Industrial application field]

The present invention relates to a housing including a frame and a door that covers an opening of the frame, and particularly relates to a door opening/closing mechanism.

Housings that mount or house electronic devices can be classified into open types, which have an opening on the side, and shielded types, which are covered with doors or the like, depending on the environment in which they are placed.

In a shielded type with such a configuration, a space is required around the casing for rotation when opening the door, etc., and consideration for the surroundings is required when installing the casing.

[Conventional technology]

As illustrated in FIG. 4, in a case with a door, the door 1 is generally attached to one end of the opening 3 of the case 2 with a hinge 4 or the like so that it can be opened and closed.

Therefore, when opening the door 1, a space 5 for opening and closing the door 1 is required, as shown by diagonal lines in the plan view of FIG.

[Problem to be Solved by the Invention 1] As explained above, when opening the door, a large opening/closing space is required around the casing to rotate with the width dimension of the door as a radius. There was a problem with poor space efficiency.

[Means for solving problems]

FIG. 1 is a side view showing the principle of the invention.

This problem is solved by providing a connecting rod 6 that rotatably connects one end of the door 1 and a predetermined position of the housing 2, and rotating the connecting rod 6 together with the IR1 to rotate the door 1. This problem is solved by the door opening/closing mechanism according to the present invention, which can move along the side wall 2a of the case and overlap.

[Effect]

By rotating the connecting rod and moving the door along the side wall of the housing, the door can be opened, and the space required for opening and closing can be extremely reduced.

〔Example〕

FIGS. 2(1) and 3(b) to 3(al to dl) are examples of the present invention.

The door opening/closing mechanism of the present invention uses, for example, a wire that rotatably connects a position 1b close to one end 1a of the door l and a position 2b close to a side wall 2a of the housing 2, as shown in FIG. A connecting rod 6 which is bent as shown in the figure is provided, and the door l
The door 1 is opened and closed by rotating the connecting rod 6 at the same time, and the figure shows the door 1 in an open state.

That is, to explain the opening/closing operation of the door 1 with reference to FIGS. 3(a) to (dl), the closed door 1 as shown in FIG. While rotating, the housing 2 is pushed outward as shown in FIG. 2(b).

Then, it rotates as shown by arrow B using the connecting rod 6 as a radius, as shown in FIG.

In order to open the door 1 in this way, it is sufficient to move it slightly against the housing 2 as shown in the figure (bl), and then rotate the connecting rod 6 and move it along the housing side wall 2a.

As described above, the door opening/closing mechanism of the present invention requires only a small space to open and close the door 1, and especially when the door 1 is opened and closed vertically in a so-called horizontal manner as shown in FIG. door l
can be placed on the top of the casing 2, making it easy to handle.

Although the above explanation was given for the so-called horizontal type shown in FIG. 2(a), the present invention is applicable to a so-called vertical type opening/closing mechanism in which the door 2 opens and closes in the horizontal direction with respect to the housing 1, as shown in FIG. 2(b). Of course, similar effects can be achieved.

〔Effect of the invention〕

As explained above, by applying the door opening/closing mechanism of the present invention to the housing, the door can be opened and closed in a small amount of space, and the efficiency of the space where the housing is installed can be improved. etc., it has a great effect so that you do not overdo it when planning the indoor space.
